Other automakers follow Tesla into rare earth metal-free powertrains
Tesla and others are looking to end the use of rare earth metals in future electric vehicle (EV) motors, with U.S., European and Japanese automakers all considering the move to help reduce reliance on China.
During the company’s Investor Day event earlier this year, Tesla’s Vice President of Powertrain Engineering Colin Campbell announced that the company’s next-generation powertrain would include a permanent magnet motor with zero rare earth metals. Automakers including General Motors (GM), Jaguar Land Rover (JLR), Nissan and more, along with the supplier BorgWarner, are all developing, researching or have already created motors with low- or zero-rare earth materials, according to a recent report from Reuters.

Nissan has taken its attempts further than previously reported in the development of new magnet-free externally excited synchronous machine (EESM) motors, which utilize an electrical current to create a magnetic field. Eventually, the Japanese automaker plans to phase out the use of rare earth metals entirely through EESM development and the use of permanent magnet motors. Nissan also currently utilizes an EESM motor in the Ariya crossover.
“This is an important contribution to making us a little more independent of China,” said Otmar Scharrer, CTO of German supplier ZF.
ZF has created an EESM motor that Scharrer said offers similar performance and overall size to those in permanent magnet motors.
Currently, the processing and mining of the 17 minerals known as rare earth metals are dominated by China, and many have sounded the alarm on relying too heavily on the country — especially after the government announced a recent export ban of gallium and graphite, both of which are crucial for EV production.
There are also sustainability reasons to move away from the use of these minerals, along with those related to bolstering the home supply chains of individual markets. Other rare earth materials like neodymium and dysprosium require the use of solvents and generate toxic waste, opposing current environmental standards and goals.
Detroit-based company Drive System Design is working on motors free of rare earth metals with three different automakers, and the firm’s Director of Engineering Business Development, Ben Chiswick, also highlights the environmental benefits of the shift.
“If you get it right, you’ve got a much more sustainable product,” Chaswick said.
BMW has reportedly conducted several years of research into motors without rare earth materials.
“It was not a home run… but it works very well without rare earths,” said Uwe Deuke, BMW’s lead engineer for the EESM motor being developed for its next-generation vehicle.
Even automakers that aren’t phasing out rare earths entirely are reducing their content dramatically in upcoming EV designs. Mercedes-Benz, for example, will use almost no heavy rare earth materials in its next-generation EV, although it will still be a permanent magnet motor using a small amount of the minerals.

Anti-Tesla union leader ditches X, urges use of Threads instead
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Anti-Tesla union leader exits X
In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.
“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.
Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant.
“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.
IF Metall sees Threads as an X alternative
After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.
Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.
“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.
Despite many recent rumors and various reports, Elon Musk confirmed today that SpaceX is not developing a phone based on Starlink, not once, but twice.
Today’s report from Reuters cited people familiar with the matter and stated internal discussions have seen SpaceX executives mulling the idea of building a mobile device that would connect directly to the Starlink satellite constellation.
Musk did state in late January that SpaceX developing a phone was “not out of the question at some point.” However, He also said it would have to be a major difference from current phones, and would be optimized “purely for running max performance/watt neural nets.”
Not out of the question at some point. It would be a very different device than current phones. Optimized purely for running max performance/watt neural nets.

While Musk said it was not out of the question “at some point,” that does not mean it is currently a project SpaceX is working on. The CEO reaffirmed this point twice on X this afternoon.
Musk said, “Reuters lies relentlessly,” in one post. In the next, he explicitly stated, “We are not developing a phone.”

Musk has basically always maintained that SpaceX has too many things going on, denying that a phone would be in the realm of upcoming projects. There are too many things in the works for Musk’s space exploration company, most notably the recent merger with xAI.

A Starlink phone would be an excellent idea, especially considering that SpaceX operates 9,500 satellites, serving over 9 million users worldwide. 650 of those satellites are dedicated to the company’s direct-to-device initiative, which provides cellular coverage on a global scale.
Nevertheless, there is the potential that the Starlink phone eventually become a project SpaceX works on. However, it is not currently in the scope of what the company needs to develop, so things are more focused on that as of right now.
Tesla has added a notable improvement to its Dashcam feature after complaints from owners have pushed the company to make a drastic change.
Perhaps one of the biggest frustrations that Tesla owners have communicated regarding the Dashcam feature is the lack of ability to retain any more than 60 minutes of driving footage before it is overwritten.
It does not matter what size USB jump drive is plugged into the vehicle. 60 minutes is all it will hold until new footage takes over the old. This can cause some issues, especially if you were saving an impressive clip of Full Self-Driving or an incident on the road, which could be lost if new footage was recorded.
This has now been changed, as Tesla has shown in the Release Notes for an upcoming Software Update in China. It will likely expand to the U.S. market in the coming weeks, and was first noticed by NotaTeslaApp.
The release notes state:
“Dashcam Dynamic Recording Duration – The dashcam dynamically adjusts the recording duration based on the available storage capacity of the connected USB drive. For example, with a 128 GB USB drive, the maximum recording duration is approximately 3 hours; with a 1 TB or larger USB drive, it can reach up to 24 hours. This ensures that as much video as possible is retained for review before it gets overwritten.”
Tesla Adds Dynamic Recording
Instead of having a 60-minute cap, the new system will now go off the memory in the USB drive. This means with:
- 128 GB Jump Drive – Up to Three Hours of Rolling Footage
- 1TB Jump Drive – Up to 24 Hours of Rolling Footage
This is dependent on the amount of storage available on the jump drive, meaning that if there are other things saved on it, it will take away from the amount of footage that can be retained.
While the feature is just now making its way to employees in China, it will likely be at least several weeks before it makes its way to the U.S., but owners should definitely expect it in the coming months.
It will be a welcome feature, especially as there will now be more customization to the number of clips and their duration that can be stored.
